3D Without Glasses

There are two main flavors of Stereo 3D (S3D) on the Web that need no glasses; Both call for the viewer to re-register his gaze to make two side-by-side pictures overlap. This is called Freeviewing.

This tutorial shows one of these two 3D viewing techniques: Cross-Eyed. The other is variously called: Parallel, Divergent, and (best of all) Wall-Eyed. In the first, the sight lines cross to overlap the pictures, in the second they do not.

Parallel is still the best for reduction of eye strain though. <3 to Parallel stereograms.

Hello, wingedsonar—

You are absolutely correct. But with the wide use of 21+" monitors, parallel side-by-sides can exceed most viewers' ability to fuse, even rubber-eyed 3D abusers (it's sad, really). Cross-eyed, or, a-hum, convergent viewing, can be taxing to the optical apparatus initially. That wet-ware is quite flexible, though, and repeated viewing usually produces something like tolerance. Perfect? nah. But it spreads the word and there's nothing lining up to replace it.

i cant do it :'(

[TroubledParty]

which 3d glasses. the red and blue ones or the newer ones. I personally like the new ones because going cross eyed hurts after a while

[MegaGreenscorpion]

It's a perfect true!!! That's a jack shit lie it WILL do the same thing even if you don't and it works like jack shit!! }:(}

Actually Crossing your eyes is dumb! i should know When I was six I crossed my eyes and had to have Surgery to get them fixed I never Crossed them ever again.

it blurs with i cross eyed!

I GOT IT but is very weak

It doesn't like, look 3-D, but like.. Really intense and different. o_O

All this time I've been doing it wrong, but now I know how to.

Check out my 'Rope Swing Crosseyed' vid

That'll die out when everyone's monitors cease to function in three years. ;)

But you have a point, unless people want to watch movies in 3" format, or from the next room back, the specialized flicker-screen technique should be refined for home use. I'm rubber-eyed myself for this, and even I'm finding at this resolution, some are very dizzying to view.
